Low325 , Congratulations with your X1 , you will be super happy with it. I just added the remote to my Lumin as i am now using my Accuphase-470 with its amp section only, and use the Leedh on the Lumin X1 which is amazing. And the remote control is really good quality , easy to set-up and enjoy.
For SFP i am thinking more and more to upgrade my switch ( Dlink ) to a Sotm as it has the SFP build in.
